I’d always thought my song about the mountain dwellers ending up on waterfront row because of rising sea levels was not to be taken too seriously. It was an apocalyptic view of what might happen if it didn’t stop raining and, moreover, not a terribly original idea as it turned out. But the risk of flash flooding from above-average rainfall is only half the problem for people living down there, at sea level.

A loyal reader, visiting the coast from cooler climes down south was discussing his theories about rising sea levels and coastal tourist locations like Noosa, given news of the Arctic region’s third winter heat wave in a row. His attention had been drawn to Greenland, where temperatures have remained above freezing at a time of year when it should be at least 30 below. Clearly such weather extremes in the fragile ecosystem of the Arctic region must accelerate the process of rising sea levels?

As The Independent reports, this is happening even though large parts of the Arctic Circle are trapped in perpetual darkness.

New global projections forecast a sea level rise of 2m by 2100, compared to a 0.74m rise in a 2013 study. So far, the forecasts that oceans would rise on average by 3mm a year has provoked a scornful debate between believers and climate sceptics. Yes, the science is not wholly believed. There are people in high places who have made naïve and disturbing statement such as “coal is good for humanity”, at a time when most scientists agree that CO2 emissions, produced largely from human activity, must be reduced.

The spectre of melting polar ice bringing an apocalyptic end to civilisation as we know it has been a favourite theme of science fiction writers for a long time. Now there is even a fiction sub-genre known as ‘cli-fi’ which has spawned many cataclysmic climate scenarios.

The spookiest forecast, before cli-fi was a thing, was The Drowned World, J.G Ballard’s second novel, published in 1962. Ballard’s main character is a scientist in charge of a floating research station, drifting above a submerged London, beset on all sides by encroaching tropical jungle. A 50th anniversary edition (with an introduction by Martin Amis) has been released and it is available as an ebook. I’ve not read it, though, relying on Peter Briggs’ review for the synopsis.

Ballard eerily conjured up a world where polar ice caps have melted and solar storms have left us in an irradiated world. Europe is a series of lagoons, devoid of human life, although the tropical bugs love it!

The most recent book in the cli-fi genre which I have read is The Ice by Laline Paull. Her 2017 mystery novel begins with wealthy tourists aboard the Vanir, traversing previously frozen Arctic oceans. The mission is to find a (now rare) polar bear, but instead they find the thawed body of an explorer who went missing years ago in mysterious circumstances.

Fiction aside, the alarming temperature rises in the frozen north have had a bizarre impact on Europe, the US and Canada in 2018, which at this time of year ought to be seeing the first thaws of spring. A day temperature of 1 degree celsius in Greenland might not seem too warm to us Aussies, but typically the days are often up to 30 degrees colder. And this is not confined to Greenland. The most northern US city (Utqiaguik, Alaska), has also been enjoying a balmy 1 degree celsius − again that’s 22 degrees above average.

Meanwhile,The Independentobserved that a relatively high pressure system over Russia and the Nordic north and a relatively low pressure system across the UK resulted in freezing Artic air being drawn towards the UK and causing exceptionally cold weather there.

The chorus of Waterfront Row ponders: “Little did I think when I moved to the mountains, I’d end up on Waterfront Row, renting out my shed to all those who fled the torrents and the foment down below.”

Imagine my chagrin upon writing and recording this song to be told (by a country music fan), that the song was similar (in theme) to Graeme Connors’ A Beach House in the Blue Mountains. I had not heard of the song but googled it (as you do).

We’re not the only ones taking ‘cli-fi’ into the realms of songwriting. Sunshine Coast songwriter Noel Gardner made up this cheery tune about the low-lying island nation of Tuvalu. He takes the role of the climate sceptic to satirise the controversy about Tuvalu and rising sea levels.

Some years back, the tiny Pacific island nation was said to be so prone to inundation its citizens might have to become New Zealanders. As it happens, some 2,400 Tuvaluans have already moved to NZ or neighbouring islands, according to a not-for-profit group that monitors world poverty.

They may have moved too soon, if, as the article below says, Pacific atolls like Tuvalu actually grow and float, becoming impervious to rising tides.

Now, a study confirms what we’ve already known – atolls, and in particular Tuvalu are growing, and increasing land area, writes Anthony Briggs. “So much for climate alarmism”.

Nevertheless, the highest elevation on Tuvalu is 15 feet and it is perpetually exposed to rising sea levels, cyclones and tsunamis.

An article in The Conversation says previous studies examining the risk of coastal inundation in the Pacific region have been conducted in areas where the rate of sea level rise is ‘average’ – 3mm to 5mm per year. A team of authors, led by The University of Queensland Senior Research Fellow Simon Albert unearthed outlying examples.

At least five reef islands in the remote Solomon Islands, where sea level rises are in the order of 7mm-10mm a year, have been lost completely to rising sea levels and coastal erosion. A further six islands have been severely eroded. These islands range in size from one to five hectares and supported dense tropical vegetation that was at least 300 years old.

Last year, new projections from the National Oceanic and Atmospheric Administration (NOAA) in the US revealed that global sea levels could rise by 2 metres by 2100 if emissions remain at their current levels. As the ABC reported, this is substantially higher than the 74cm increase proposed in a 2013 Inter-governmental Panel on Climate Change (IPCC) report. Under these new projections, Sydney’s Circular Quay, Brisbane Airport, Melbourne’s Docklands and North Fremantle would be among locations at risk. So too Stradbroke Island, the Gold Coast and Sunshine Coast, while in South Australia the seaside suburb of Glenelg would also be in trouble.

Scarier predictions have been made, with scientists taking into account the prospect of Antarctica melting, as well as the Arctic, doubling predictions of a 2m rise by 2100.

Should we care? By 2100, the youngest person I know will be 89, so maybe she will care. Her children and grandchildren definitely will.

And what does this mean for Australia, where the majority of the population live along narrow bands of coastal land on the east and west coasts?

Cape Town’s water crisis is making news around the world, but nowhere should it be ringing alarm bells more than in our neck of the woods – South East Queensland. It’s not that long ago since the Millenium Drought (2001-2009) reached a dramatic point in late 2007. Brisbane became the first Australian capital to endure Level 6 water restrictions at a time when the region’s main reservoir, Lake Wivenhoe, dropped to 15% capacity.

In Cape Town, South Africa, the town water crisis is so parlous that taps were to have been turned off on April 16, but conservation efforts by the city’s 4 million people has pushed this out to June 4. Cape Town introduced Level 6 restrictions last month. Reports from the South African capital sound a bit like conditions in South East Queensland, circa 2007-2008.

The so-called ‘Day Zero’ – when water in Cape Town’s six reservoirs drops to 13.5% – means taps will be turned off and residents will have to queue at standpipes for daily rations. (Think dystopian movies like Young Ones or The Worthy).

A news report this week described a sudden sharp shower in Cape Town (10mm or so). People were said to have rushed out of restaurants, bars and shops just to feel the rain on their faces.

Residents are being encouraged not only to limit their showers but also to have baby baths over the shower outlet to collect the grey water for recycling. As was the case in Brisbane, Cape Town residents are being discouraged from washing their cars and flushing toilets (unless really necessary).

According to our local utility, SEQWater, during our own water crisis in 2007-2008, Brisbane residents successfully halved daily water consumption to 140 litres per person under Level 6 restrictions, which included a ban on filling pools. Gardens could only be watered with buckets (with water collected from those three-minute showers). The motto, ‘if it’s yellow let it mellow’ was nailed to many a dunny door.

Conditions are tougher in Cape Town, where residents are limited to 50 litres each per day. The Guardian reported that Cape Town’s water crisis was accelerated by a drought so severe it was not expected for another 384 years. Plans to diversify with more boreholes and desalination plants are not scheduled until after 2020. The city’s biggest reservoir, Theewaterskloof Dam, has mostly evaporated or been sucked dry since the drought began in 2015. The shoreline is receding at the rate of 1.2 metres per week, The Guardian reported.

Tucked away in its two-page feature on Cape Town’s water crisis was the colourful but completely unhelpful statement from an un-named homophobic pastor who blamed the drought on gays and lesbians.

Back home, South East Queensland’s water crisis in 2007-2008 ushered in a new era of water management, resulting in the SEQ Water Strategy, which set a water consumption target of 200 litres per day.

SEQWater spokesman Mike Foster says the biggest single change since the Millenium Drought was construction of a 600 km reverse flow pipeline network that allows treated water to be moved around the region. The utility also now has a ‘drought-ready’ strategy which is triggered when storage falls to 70%. Currently the region’s dam levels overall are at 75.9%, so nobody is losing sleep over the average per capita daily water consumption of 184 litres.

FOMM wrote in March that water levels at our local dam, Baroon Pocket, had dropped to 46%. SEQWater supplemented the Sunshine Coast through an extended dry spell in 2017. Baroon Pocket Dam is now back to 78% (this photo of the spillway (January 2011) shows what can happen when 750mm falls in one month.

Blame it on climate change if you like, but the Sunshine Coast region has recorded below average annual rainfall in three of the last six years. What really did the damage was an eight-month stretch from July 2016 to February 2017 with an average rainfall per month of only 43mm. Source: Bureau of Meteorology monthly rainfall.

The South East Queensland Water Strategy aims to maintain regional water security into the future through management and operation of a water grid including a recycling facility and a desalination plant.

SEQWater owns and operates 26 dams, 51 weirs, and two borefields, including 12 key dams which supply as much as 90% of the region’s drinking water. Foster says SEQWater is now planning for far worse events than the Millenium Drought.

“Cape Town never thought they would experience more than two failed wet seasons in a row. South East Queenslanders never thought we would experience two failed wet season in a row either.

“But we went through the Millenium Drought and nearly a decade of failed wet seasons.”

Foster says that if SEQ was again faced with a Millenium Drought scenario, the strategies put in place would allow water supply to be maintained with medium level restrictions.

Meanwhile, in far more parched countries

You might feel relieved to learn that Australia was not one of 33 countries identified by the World Resources Institute as facing extreme water stress by 2040. However, Australia is one of six regions facing increased water stress, water demand, water supply, and seasonal variability over the next 22 years.

The top 11 water-stressed countries in 2040, each considered extremely highly stressed with a score of 5.0 out of 5.0, are projected to be Bahrain, Kuwait, Palestine, Qatar, San Marino, Singapore, United Arab Emirates, Israel, Saudi Arabia, Oman and Lebanon.

The 2015 report forecasts rapid increases in water stress across regions including eastern Australia, western Asia, the Mediterranean, the Middle East, the North American West, northern China, and Chile.

Nothing focuses the mind on the need to conserve water more than a summer camping holiday in a water-scarce national park. At the Bunya Mountains national park, east of Dalby, bore water is available in the national park camp ground. But it is labelled ‘non-potable’ and visitors are advised to boil and/or sterilise the water before using. We have a 60 litre tank under our caravan and we also take two 10-litre containers as back-up. Even so, after five days the van tank was less than half full and by the time we drove home on a stinking hot Sunday, we were sharing the last few mouthfuls from a water bottle.

Fine, just walk into the Kilcoy IGA and buy some bottled water, right? Maybe not. In Cape Town, supermarkets were forced to introduce a per customer limit after a big run on bottled water.

You may recall I was enthralled a while ago by Ben H Winters’ series, The Last Policeman. This cli-fi trilogy depicts the urban chaos developing as the population wait for the cataclysmic arrival of an asteroid which will destroy the planet.

Winters expertly conjured up underlying tensions between survivalists, conspiracy theorists or escapists who have “gone bucket list” or found easy ways to do themselves in. Then there are those with no particular moral code. As of the policemen in Winters’ second book says: “Just you wait until the water runs out…”

Nobody can call out an errant politician better than former Liberal Opposition Leader John Hewson. In the 22 years since he resigned from politics, Hewson has become a respected academic, the darling of TV panel shows like Q&A, and a regular on the celebrity speakers’ circuit. Yesterday, Hewson was a keynote speaker at Griffith University’s two-day summit, Integrity20.

Who better to address the opening topic “Post-Truth, Trust and the Ethics of Deceit?” Hewson has been speaking out about fake news and the propensity of politicians to stray from the facts, long before Donald Trump made it a catch phrase. He is also an advocate for evidence-based public policy, often identifying where politicians have used models and commissioned reports to suit their version of the facts.

So to Hewson’s opening address yesterday, where he used the climate change debate to support his argument for ‘evidence-based public policy’.

“We had a very hard-line position as a response to the climate challenge back in the early 1990s. I was calling for a 20% cut in emissions by the year 2000 off a 1990 base. We are yet to know how we are getting the 5% reduction in emissions by 2020 off a 2000 base. And of course, we’re committed under the Paris Accord to cut emissions by 26% to 28% by 2030.

“What’s happened over that period is drift – the issues have been left to drift. Housing affordability’s been left to drift, the climate response has been left to drift and the final line of that drift is the mess we have in the energy sector. Electricity and gas prices are running away to the point where the average household is struggling to afford to pay its power bills.

“These are the outcomes of negligent government over a very long period of time.”

Hewson believes the situation can be turned around, but it will take some years to reverse the damage. He said what the country needed was an honest debate about leadership.

“And leadership is going to be about telling people honestly the way it is. To get good policy up we have to educate people to accept the magnitude of the problem.

“But we don’t have any debate now in this country – it’s all negative. One side puts its hand up and says let’s do X and the other side immediately says no.”

One in three voted for someone else

He said people had lost faith in the two-party system. In the last election, one in three people did not vote for one of the major parties. The protest vote was not just something that had happened only in Australia, he added, citing Brexit, the US, France and Germany as recent examples.

“It’s a longer term trend and it will get worse before it gets better.”

The path to restoring voter confidence, he said, was by focusing on the issues that affect people – the cost of living, health, housing, childcare and education.

But the main problem was that the ‘wrong people’ were in government.

“If you asked them why they went into politics, they’d say to make a difference and leave a better world for their grandchildren.

“And then they do the opposite.’

Hewson, who will be 71 next Sunday, had a distinguished career in politics. He was leader of the Australian Liberal Party and Leader of the Opposition between 1990 and 1994. Before and after politics he has worked as a senior economist for organisations, including the Australian Treasury, the Reserve Bank and the International Monetary Fund.

In this context, it seems uncharitable to recall that in 1991 he advocated an unpopular goods and services tax. He lost the 1993 election to Paul Keating over the “Fightback Package”, of which GST was a central element. Ironically, Paul Keating (who first advocated a GST in 1985), shamelessly exploited public opinion to thwart Hewson.

All that aside, Hewson at least clearly outlined what he was going to do in 1991-93 and stuck to it. He is known still as a straight shooter, a man who once said he lived in hope of ‘spin-free politics’.

Day one of the Integrity20 Summit was not just about politics and truth. ABC presenter James O’Loghlin chaired a panel discussion about solving the world’s problems through innovation.

Inventor and futurist Mark Pesce showed a short video of a robot working on a farm in Indonesia. He described it as just two wheels, an axle and a smartphone on the end of what looks like a selfie stick, collecting data and producing crop reports. These robots cost about $2,500 and can be shared around a farming community. He also demonstrated how 3D printers, aligned with a simple robot used in smart phone technology, can reproduce all the plastic parts to build another 3D printer. Eventually, robots will also be able to assemble the printers – and that’s just the edges of the innovations universe.

CSIRO scientist Stefan Hajkowicz said the impact of Artificial Intelligence on the future of work had been greatly over-stated. He thought there were many areas where robots and humans would work side by side – in hospitals for example. The robot would do the blood test and the nurse would soothe the patient’s concerns.

But it turns out robots are crap at irregular tasks we humans take for granted, A robot cannot tie your shoelaces, for example. And, as Hajkowicz added, they can’t fold towels. They tried to get a robot to fold a towel. It took 20 minutes and did the job badly.

Today I attended the final full-day session of Integrity20, hastily scribbling notes and pressing stop/start on my hand-held recorder. You may wonder how I met my deadline – marvel at my prowess.

Have you ever noticed, after giving your dog a bath, how it will head straight for the nearest patch of renewable energy? Ours has a favourite sunny spot next to the dining room table where he will happily bask, while our solar-powered camping lamp, calculator and torches are recharging on the window sill.

Free sunshine – what’s not to like? As it happens, we have been preparing our little caravan for a weekend music festival in the bush. The 160 watt portable solar panel slides snugly under the bed. At $159, this has proved to be a worthy investment for our outback and bush music weekend adventures. It means you can keep topping up the caravan’s battery (if the sun is shining) and go to bed early if it’s not.

We are not expecting rain. No-one is expecting rain.

Australia’s Bureau of Meteorology has confirmed the winter just past was the hottest since records began in 1910. It was also the 9th driest winter on record. The average maximum temperature was almost 2 degrees above the long-term average.

Meanwhile, Texas is suffering unprecedented flooding courtesy of Hurricane Harvey, the reporting of which has somewhat overshadowed devastating monsoon flooding in South East Asia. So far, in the latter disaster area, 1,200 people have been killed and almost two million children were unable to get to school.

As we ironically say in the privacy of our own home – “Just as well there’s no such thing as climate change, then!”

Now all, some of, or only a small part of these extreme weather events could be ascribed to global warming/climate change, which, 97% of scientists agree, is mostly caused by human activity.

Despite this consensus on behalf of an apparently overwhelming majority of scientists, sceptics disagree. I happened to read that former Prime Minister Tony Abbott is set to deliver a speech, “Daring to Doubt,” at an annual climate sceptics group meeting in London on October 9.

You might remember Tony Abbott – his reign as PM at one year and 361 days (cumulative terms), was longer than that of Harold Holt and Billy McMahon, but not by much. Abbott the Climate Change Sceptic is infamous in some quarters as the man who canned the government-funded Climate Commission as part of a Budget cost-cutting exercise.

The Climate Commission bounced back as the privately-funded Climate Council. A new report by the Climate Council concludes that the individual States are going their own way, with mixed results.

South Australia is a clear leader in the renewable energy field, the stakes raised by the government’s decision to replace ageing coal-fired power stations with a 150 megawatt solar thermal power plant.

FOMM foreshadowed this in 2014, when the SA government was trying to negotiate the future of the coal mine which fed its Port Augusta power stations. Now, after five years of lobbying and debate, the SA government is aiming to invest $650 million in renewable energy.

It hardly seems worth mentioning that 1,900 kilometres away, the Queensland Government, in a contrarian move, remains committed to the country’s largest Greenfield export coal mine. The Carmichael mine, which includes a dedicated railway line to take coal north to Abbott Point, is deeply unpopular among environmental groups because of the potential damage it could cause to the Great Barrier Reef, both by the number of ships traversing the narrow channels, and through coral bleaching as a result of human-induced temperature increases.

On the other hand, Queenslanders’ love affair with domestic solar panels is demonstrated by the fact that 32% of households are covered in 2017. Lobby group Solar Citizens (almost 100,000 members), welcomed last week’s decision by the Queensland Government to increase the regional feed-in tariff (FiT) program. This will allow solar systems up to 30kW to receive 10.1c per kWh – six times more than what was previously agreed.

Solar Citizens has an ambitious target of one million solar roofs by 2020.

“Queenslanders know a sensible idea when they see it – with 520,000 solar homes, our State has the highest rooftop solar uptake in the country,” a spokeswoman said.

However, critics of domestic solar energy say the flaw is that those who can afford to become self-sufficient do so, and those who cannot end up paying disproportionately more for energy.)

This week, the Climate Council presented its annual ‘state of the States’ renewable energy report. CEO Amanda McKenzie said the State survey showed a major step up from last year. All States and Territories (apart from WA), have strong renewable energy or net zero emissions targets. South Australia is building the world’s largest lithium ion battery storage facility, and over 30 large scale wind and solar projects are under construction across Australia in 2017.

“The good news is that many States are surging ahead and doing the heavy lifting for the (Federal) government.”

Last week, the Victorian government flagged new legislation which would increase its renewable energy target to 40% by 2025. There is also an intermediate plan to lift Victoria’s clean energy target to 25% by 2020.

So yes, it does seem as if individual States (and Councils) are setting their own renewable energy policies, in the absence of clear leadership at a national level.

Noosa Mayor Tony Wellington did not miss an opportunity to talk up his region’s commitment to solar panels. Noosa Shire, which de-merged from the larger Sunshine Coast Regional Council (SCRC), claims 9,000 households in Noosa Shire have solar installations, which is better than the State average. Cr Wellington told the Sunshine Coast Daily Noosa’s goal was to be ‘carbon neutral’ by 2050.

Not to be overshadowed, the SCRC opened a 15 megawatt solar farm in July. The SCRC was the first local government in Australia to offset 100% of its electricity consumption with energy from a renewable source.

But what can humble citizens do, as pro-coal lobbyists clash swords with the solar and wind farm warriors? The go-it-alone mentality arises from a failure on the part of our Federal Government to stimulate investment in the renewable sector. Australia has already promised, under the 2015 Paris Climate Agreement, to reduce greenhouse gas emissions by 26% to 28% on 2005 levels by 2030. But Tony Abbott’s call as PM to reduce the renewable energy target (and now he advocates scrapping it altogether), was unhelpful.

Whatever way you judge it, a former PM addressing the Global Warming Policy Foundation is not a good look. The last Australian PM to do so was John Howard in 2013 (when he claimed global warming had stalled and was sceptical about the possibilities of an international agreement on climate change).

There have already been reports in the UK media which seized on old quotes by Mr Abbott referring to climate science as ‘bullshit’ and recycling his coal is ‘good for humanity’ comment.

As readers will know, we spent a week out at Carnarvon Gorge in July, a time of year when it is common for the temperature to dip below zero at night. We packed accordingly, then spent four nights kicking off the doona and keeping each other awake as the mercury stayed above 15.

It should be cool at night for the Neurum Creek Folk Festival, but I packed my shortie pyjamas, just in case there is such a thing as climate change.
